Patented Oct. 14, 1930 GEORGE Mosrlsor Fiennes ISLAND, NEW YORK FOUNTAINPEN Application fued June 11,

a This invention appertains to fountain pens a* ofthe self-filling typeand has for one of its primary objects the provision of a novel andsimple means for insuring the filling of the y.barrel of the pen, 'thedevice being so constructed as to Vpermit a maximum amount of ink to becontained in the barrel.

" 'Another important object ofy my inventiony is the provision ofpositive means for drawing the ink in the barrel,'sa`1d means embody- *Ying apiston sleeve slidably mounted within `the barrel and operable uponoutward slide` y'the ink into the barrel..

ing movement thereof'in the barrel to draw "A further salient object ofmy invention is the provision Of'positively lockiligthe slid-v f ino`iston sleeve in the barrel in its ino aer- 'attive positionagainstaccidentaly movement Y while'the penis in use and means forlimiting .the outward sliding movement of the pist-On' sleeve when ythesaine isbeing Operated toy draw the ink into the barrel.

VA still further object of my invention isr to provide novel means forarranging the barrel and the piston sleeve relative to one another sothat the leakage of ink between the barrel and sleeve will be precludedand so that acompact structure will be had.V

A still further Object of my invention is to provide a self-filling penof the above. char- 'acterj which will be durable and efficient in use,onelthat will be simple-and easy' to manufacture, andy one which can beplaced upongthe market at a reasonable cost. s

ZWith these and other objects in view, the

linvention `consists. in the novel construction,

i arrangement and formationof parts, as will be hereinafter morespecifically described,

claimed, and illustrated in the accon'lpanying drawing, in whichdrawing:

trating the novel locking means and guide for the piston sleeve;

Figure 4 is an enlarged fragmentary longitudinal sectional view throughthe improved pen illustrating the novel locking means be. tween thebarrel and piston sleeve, the piston sleeve being in its locked positionFigure 5 is a detail transverse section through the barrel and sleevetaken on the line 5- 5 of Figure Ll looking in the direction of thearrows;

Figure 8 is a transverse section taken on the line 8 8 of'Figure 7looking in the direction of the arrows, and s Figure 9 is an enlargedtransverse section taken on the line QMS) of igure l looking in theldirection of the arrows. i

Referring to the drawings in detail, where! in similar referencecharacters designate Oorresponding parte throughout the several views,the letter A generally indicates my improved fountain pen whichcomprises a barrel l0 open at its rear end and having its forward endcontracted for receiving the sleeve plug l1 for the reception of thefeeder bar l2 and pen point or nib 13. y

Slidably mounted within the barrel l0 is a piston sleeve l5 whici isclosed atits outer cndby a suital'e head 16 which forms in con junctionwith the'sleeve a stop shoulder 17 for engaging the eurer end of thebarrel when the sleeve inV innermost position, the outer surface of thehead being of the same diameter as'the outer Vdiameter of the barrelsurface of the barrel.

From the description so far, it is obvious 'grasped and the pistonsleeve pulled outward from the barrel, a 'suction will be caused in thebarrel thereby permitting the drawing of ink into the barrel i crossslot opening out through the opposite faces of the cross bar, thelocking lugs being adapted to be received in the' cross slot upon theregistration of the first slot With said lugs, the barrel being adaptedto be turned to an arc of 180o to dispose the lugs in the cross slot atright angles Vto the first slot, whereby j to bring about locking of thesleeve Within the barrel.

' ried by the inner end of said rod and including a pluralityofrresilient arms, and radially lextending lugs on the terminals of saidarms, the lugs being adapted to be sprung into said 5. A fountain penvof the self-viilling type,

, barrel having its rear end open and provided Witha lock groove on itsinner surface adjacent to the innerk end thereof, a piston sleeveslidably mounted in the said barrel and having a closing head on itsouter end, a guide rod for said sleeve, a cross bar carried by the Ysleeve adjacent to the inner end thereof slid- `ably mounted on saidrod, a foot carried by Y the inner end of said rod and including aplurality-of resilient arms, radially extending lugs. on the terminalslof said arms, the lugs being adapted toV be sprung into said groove,and means for detachably locking the rcross bar to the rod when thepiston sleeve is in its innermost position. f

interlocking members carried respectively by the interior ofthe pistonsleeve and the for- Ward end of the barrel engageable when thepistonsleeve is in its extreme forward positionin said barrel. f

V7. A fountain pen of the self-filling type 1 comprising a barrel havingan ink feeding and Writing mechanism at the'forward end thereof andhaving its rear endopen, a piston e sleeve slidably mounted Within saidbarrel, an

axially disposed.guidel rod in said barrel, a locliiigdevice carried bythe interior of the piston sleeve for locking engagement with thev rodWhen thepiston sleeve is in its' eXtreme forward position, and means onsaid rod at the rear end thereof for llimiting the outward motion ofsaid piston sleeve.
